Is it safe to use kms activator while you use a QT bitcoin wallet on windows?
can kms activator stole your private key?
Why hustle bypassing windows activation system when there is linux?
Anyway kms activator is harmless as of now, Most people have used it without issues of information theft so far but of course windows will always warn you that it's harmful because it's bypassing their activation system. However, to be on a very safe side, avoid the activator at all costs. When it comes to money and wallets, anything can happen and hackers can do anything to get that money of yours.
So always have it in mind that Kms activated OS = Unsecure OS.
